Brief Description: Aileron torque tube and TruTrak roll servo
23-7, Steps 1, 2, 3, 4, & 5
Brad assisted me today.
Insert WD-1014C Torque Tube Collar (which is bolted to the WD-1014 FORWARD Forward Torque Tube Subassembly) through the forward side of the 1 1/8 inch diameter hole in the spar web.
Angle the WD-1014C Torque Tube Collar down as it extends aft through the hole in the spar web and slip the WD-1014 AFT Aft Torque Tube Subassembly over the torque tube collar. Engage the WD-1014 AFT Aft Torque Tube Subassembly and the torque tube collar far enough to allow the threaded ends of the torque tube subassemblies to be inserted into the flanged bearings riveted into the wing structure. Disengage the aft torque tube subassembly and torque tube collar slightly as the threaded ends of the torque tube subassemblies are inserted into the bearings.
Install washers and nuts on the WD-1014 FORWARD and WD-1014 AFT Torque Tube Subassemblies.
Check to see if the bolt holes in the WD-1014 AFT Aft Torque Tube Subassembly and WD-1014C Torque Tube Collar line-up properly. If the bolt holes in the aft torque tube subassembly and torque tube collar misalign in the forward/aft direction then AN960-416 or AN960-416L washers should be installed between the torque tube subassemblies and the flanged bearings as required to eliminate the forward/aft hole misalignment. There should be little or no pre-load on the wing structure when the aileron torque tube installation is complete. Install bolts, washers, and nuts as shown in Figure 1 to attach the aft torque tube subassembly to the torque tube collar.
Figure 2 shows the "neutral position" of the WD-1014 FORWARD Forward Torque Tube Subassembly. The correct rigging of the aileron actuation system is defined by the forward torque tube subassembly, WD-421 Aileron Bellcrank, and Aileron all being in their neutral positions at the same time.
We also installed the TruTrack roll servo in the right wing.
